Roller coaster prices

The RAC also warned that a high degree of volatility in wholesale fuel prices means drivers could face further price fluctuations at the pumps.

RAC Spokesman Rod Dennis said: “July saw a return to rising prices at the UK’s forecourts, following some price cuts in the previous month – the roller coaster effect of rising and falling prices that drivers will have witnessed in recent months is certainly in full swing.

“The volatility of the price of a barrel of oil, and in turn wholesale fuel prices, makes it difficult to determine where prices might go next.

“What is certain, however, is how much more expensive it is to fill up a car this summer compared to last year.”
